Parameters

savedState
Type: SystemObject

An Object that represents the control state to be restored.

Remarks

This method is used primarily by the .NET Framework infrastructure and is not intended to be used directly from your code. However, control developers can override this method to specify how a custom server control restores its view state. For more information, see ASP.NET State Management Overview.

Examples

The following example overrides the LoadViewState method for a custom ASP.NET server control. It creates an Object array to contain the view state information passed in the savedState parameter, and then calls the base implementation of the LoadViewState method for the first index location of the array. It assigns the values stored at the next two index locations to variables named UserText and PasswordText, respectively.

Protected Overrides Sub LoadViewState(savedState As Object)
   If Not (savedState Is Nothing) Then 
      ' Load State from the array of objects that was saved at ; 
      ' SavedViewState. 
      Dim myState As Object() = CType(savedState, Object())
      If Not (myState(0) Is Nothing) Then 
         MyBase.LoadViewState(myState(0))
      End If 
      If Not (myState(1) Is Nothing) Then
         UserText = CStr(myState(1))
      End If 
      If Not (myState(2) Is Nothing) Then
         PasswordText = CStr(myState(2))
      End If 
   End If 
End Sub
protected override void LoadViewState(object savedState) 
{
   if (savedState != null)
   {
      // Load State from the array of objects that was saved at ; 
      // SavedViewState. 
      object[] myState = (object[])savedState;
      if (myState[0] != null)
         base.LoadViewState(myState[0]);
      if (myState[1] != null)
         UserText = (string)myState[1];
      if (myState[2] != null)
         PasswordText = (string)myState[2];
   }
